BENHARD YOGH, OF ST. LOUIS, MISSOURI.

STEAlVl ENGINE FOR MINING PURPOSES.

SPECIFICATION forming part of Letters Patent No. 286,105, dated October 2, 1883.

Application filed April 9, 1883. (No model.)

To all whom it may concern Be it known that I, BENHARD YOOH, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in Steam-Engines for Mining Purposes, of which the following is a full, clear, and eX- act'description, reference being had to the accompanying drawings, forming part of this specification, and in which Figure 1 is a side elevation of my improved mining-machine. Fig. 2 is a horizontal section on the line 2 2, Fig. 1. Fig. 3 is a detail vertical longitudinal section. Fig. 4 is a detail vertical transverse section.

My invention relates to a receiver placed upon the machine, into which the air or steam is discharged before entering the machine, as more fully described hereinafter.

My invention consists in points of novelty pointed-out in the claims.

Referring to the drawings, A represents the frame of the machine, and B the supportingwheels.

Q represents the main cylinder of the machine, and Q its valve-chest.

R represents the cylinder of the main-valve motor, and R its chest.

S represents a receiver placed upon the machine, and communicating with the chest Q by means of a port, T, (see Fig. 4,) and with the chest B through means of a port, U. (See Fig. 3.) These ports are provided with plugvalves T U, respectively (See Figs. 3 and 4.) The valves are secured in bushings VNV, preferably, which are screwed into the sides of the receiver, as shown. The valves taper outward, the openings in the bushings being correspondingly tapering, so that the pressure on the inside tends to keep them tight. They have operating-levers T U (See Figs. 3 and 4.) The valves are located some distance from the bottom of the receiver, so that dirt and any condensed steam there maybe discharged into a the receiver can settle in the bottom of the receiver, and not be carried into the working parts of the machine, as is the case where the supply-pipe communicates directly with the chests. Dirt gets into the supply-pipe, when it is disconnected from the machine, in moving the machine from place to place, and then when the pipe is connected to the machine again and the air turned on the dirt is blown into the machine, in my case into the receiver.

X represents a nipple for connecting the supply-pipe with the receiver.

Y represents a blow-01f cock near the bottom of the receiver, for the discharge of dirt and water.

I claim as my invention 1. In a mining steam engine, a receiver placed upon the machine for the purpose mentioned, and communicating with the valvechests by means of suitable ports connected to the receiver above its bottom, substantially as described.

2. In a mining steam-engine, a receiver placed upon the machine for the purposementioned, and communicating with the chests by means of suitable ports provided with tapering plug-valves, through which the ports pass, substantially as shown and described, for the purpose set forth.

3. In amining steam-engine, the combination of main chest Q, small chest R, and receiver S, with which the supply-pipe or hose connects, having .ports T U communicating with the said chests, and provided with plugvalves T U, tapering outward, so that the pressure in the receiver will tend to keep them tight, as set forth.
